I agree with Eli.  We should trust external record layout to the extent that it generates a valid layout, but if it generates something with overlapping fields, or that runs outside the claimed bounds of the type, we'll just end up crashing in IRGen.  I assume those things are expressible in DWARF; it'd take a bunch of sub-optimal representations to make them impossible.  It's probably clang's responsibility to detect that — maybe we ought to do a special sanity check on external layouts before we feed them into `RecordLayout`.
